This line served the area between Cardonald
and Renfrew. Renfrew Transit Depot, Deanside Transit Depot, Renfrew Harbour,
Renfrew Power Station and the large King George V dock were served. Deanside
Transit Depot is still open and served by the line. The area (outwith Renfrew)
was relatively undeveloped until the dock was opened. Recently the Braehead
Shopping Centre was opened to the north of the Deanside depot.

The depot at Deanside Transit is the reason
why part of the line remains open. Trains are taken from the junction at Cardonald
to the former station at Deanside and from there reversed into the transit depot
sidings.
